Desert Locust Bulletin 559 Highlights Ongoing Challenges in Africa

The Desert Locust Bulletin 559 indicates ongoing outbreaks in the Western Region, particularly in Algeria, Libya, and Tunisia. Despite a decline in populations along the Red Sea, some breeding is still occurring in southern Egypt and northern Sudan, with forecasts of new swarms likely moving south in June. Control operations significantly increased in April, emphasizing the need for continued management in affected areas.

The recent Desert Locust Bulletin (559), issued on May 7, 2025, reveals an ongoing crisis in the Western Region of Africa. Throughout April, reports indicate that Desert Locust outbreaks intensified, particularly in southern Sahara and Northwestern Africa. Adult groups and small swarms have been moving northward across Algeria, Tunisia, and Libya, with additional sightings in Morocco, northern Chad, and Niger. Meanwhile, spring breeding has continued, resulting in the emergence of new hoppers and bands across these regions.

In the Central Region, however, there has been a decline in locust populations along both sides of the Red Sea. Despite this, southern Egypt and northern Sudan still registered the presence of small adult groups, swarms, and some hopper clusters. Notably, some laying activity was also reported in Saudi Arabia’s interior, an area that may be facing increasing locust threats as conditions evolve.

The forecast indicates that spring breeding is anticipated to persist in Algeria, Libya, Morocco, and Tunisia. There is a significant potential for new adult groups and small swarms to emerge in May. This new generation of locusts is expected to begin migrating south toward the Sahel as early as June, propelled by expected rainfall in the region.

Small-scale breeding could also remain active along the Nile Valley in northern Sudan and southern Egypt, potentially leading to new locust migration into summer breeding areas by June. Similarly, in Saudi Arabia’s interior, limited spring breeding is predicted to continue with the emergence of new adults as the month proceeds.

Control operations, which are vital to managing these infestations, have more than doubled—reaching 34,436 hectares in April, up from 17,962 hectares in March. This highlights the ongoing need for effective measures to combat locust populations across affected areas, as the situation remains precarious. There are currently no significant developments expected for the Eastern Region.

In summary, Desert Locust outbreaks are continuing to pose a threat in various regions of Africa, particularly the Sahara and Northwestern areas. The noticeable increase in adult groups and spring breeding requires ongoing control efforts. As forecasts predict more breeding and movement southward, regional authorities must remain vigilant and proactive against possible locust invasions. It’s clear that the situation is developing and consistent efforts will be critical in the coming months to manage this challenge effectively.
